All wells must be registered prior to drilling.
Well drillers can create their own accounts and still submit on behalf of well owners. If the well requires a permit, the permittee must apply for a permit before submitting the Well Registration application. A well owner, well operator, or water well driller cannot drill any well without the approved registration form filed with the District.
We recommend the email used for this account to be accessible in the long-term.
Use this application for new wells, previously permitted wells, and original application of an existing well.

Groundwater credits earned through the award-winning water conservation program can be used to offset the Subsidence District’s regulatory requirements. For every sponsorship in the program, the District will issue 84,000 gallons of groundwater credit.
Click here for more information on how to sponsor.Â
The Applications for Groundwater Certificate Replacement and Acknowledgement of District Regulatory Requirements require special handling and must be downloaded, completed, and mailed to the district office.

Mailed applications or applications submitted in person will still be accepted. Â
All permit, rebate, and groundwater credits forms are now available in the Portal.

- Current permit holders must use the email address associated with their well number to create an account.
- If you are not the current permittee or well owner, we will require permission (in the form of a letter or email) from the existing permittee or owner before you can be added to the account.
Over-Conversion Credits (OCCs) are offered to permittees with an approved Groundwater Reduction Plan (GRP) upon submission of proof that the permittee used more alternative water than required by the regulatory plan during the permit term.
OCCs may be earned by permittees whose total over conversion exceeds 10MG and GRP administrators. OCCs for Regional Water Suppliers are earned through the permit reconciliation process described in the District Rules. OCCs may be earned through any combination of alternative water use, including treated surface water, reclaimed water, or other District-approved alternative water management strategy.
Specific requirements and conditions for the transfer of OCCs are set forth in the District Rules and Regulatory Plan.
Permittees can sponsor the HGSD Water Conservation School Program in exchange for Series B Credits, which can be applied during the permit renewal process to increase groundwater use without increasing the permit rate.
Sponsorships are priced at $40 per student each school year.
Each sponsorship will earn the permittee 84,000 gallons in Series B Credits that may be applied for an additional 30% groundwater use in the permit term.
Series B Credits are valid for 20 years from the date of issuance.
Municipal Utility Districts and water providers may sponsor the school program through interlocal agreements. Learn more here!
It is possible to purchase credits on the open market. The District maintains a list of organizations/individuals who have notified the District of their willingness to sell their credits to a third party. The District does not participate in the resale of credits. Please contact the District at 281-486-1105 or info@subsidence.org if you would like more information on credit transfer and purchase.
The District’s fees are intended to operate as an economic disincentive to producing groundwater as one of the available regulatory tools. The Regulatory Plan provides a permit fee structure that includes a Base Fee and a Disincentive Fee.
Base Fee – This fee is applied to all of a permittee’s authorized groundwater withdrawals. Funds obtained from the collection of base fees are used to cover the costs of issuing permits and performing other regulatory functions of the District.
Disincentive Fee – In addition to the base fee, a disincentive fee will be applied to groundwater withdrawals that exceed a permit limit. The purpose of the disincentive fee is to create an economic incentive for permittees to take steps to ultimately reduce groundwater use. The disincentive fee is applied in each permit year that groundwater reduction requirements are not met. The District periodically reviews the disincentive fee rate to ensure the rate encourages compliance with this Regulatory Plan and makes adjustments as needed.
HGSD’s Regulatory Plan provides several solutions to avoid disincentive fees, including Groundwater Credits, Groundwater Reduction Plans, and Groundwater Conservation Plans. Discover more information about these solutions in the District’s Rules.

Yes, as long as the groundwater credits are valid and have not expired, they can be combined.
Although the District no longer issues Series A groundwater credits, there are entities that are willing to sell their Series A groundwater credits. Please contact the District if you would like information on those entities that have notified the District that they are willing to sell their Series A credits.
Prior to 2001, the District issued Series A credits, which could be used for 100% of a permittee’s total water demand and expired 40 years from the date of issue. After an evaluation of the credits potential impact on the District’s mission to prevent future subsidence in 2001, the District discontinued issuing Series A groundwater credits and replaced them with the Series B groundwater credits.
Approximately four months prior to the expiration of your permit, the District will mail you a permit renewal application form. This form must be completed and returned to the District along with the renewal application fee. Renewal applications can also be completed online, but the application will not be processed until the application fee is received.
The renewal application form will require you to enter the amount of groundwater you pumped from your well during the previous 12-month period and the amount of water you purchased from other sources. If you have access to alternative sources of water, you will be required to submit copies of water bills to verify the amount of water purchased from other sources.
The District is required to consider many different factors when establishing the groundwater allocation for each permittee. Some considerations include the following:
- The amount of groundwater requested by applicant
- Location of the groundwater well
- Availability of alternative water supply
- Participation in a groundwater reduction plan
- Use of groundwater credits to offset groundwater pumpage
Each situation is unique. Please contact the District permitting staff if you have further questions.
Most water wells in Harris and Galveston counties have been required to be permitted since 1976. After the 1993 legislative session, changes were adopted regarding which wells must be permitted by the District, resulting in an increase in the number of wells subject to permitting. In an effort to notify well owners of the changes in the permitting requirements, the District published notices in the newspaper, posted notices at the county courthouses, and held a public hearing to receive public comment. Despite these public outreach efforts, unpermitted wells are still periodically discovered by District staff during routine inspections throughout the District.
If a well serves anything other than one house, a permit is required. However, a permit may be required for a well that serves a house, depending on the following:
- What diameter is the well
- Where it is located
- When was it drilled
There are other exceptions spelled out in the District’s Rules. Regardless of whether a well needs a permit, it must be registered with the District before it can be drilled.
